Listening to the Radio?

According to the latest research:

Mental activity such as crossword puzzles, reading or listening to the radio may slow the decline of cognitive skills initially, but speed up dementia later in old age, according to new research.

………

Researchers evaluated the mental activities of 1,157 people age 65 or older who did not have dementia at the start of the 12-year study. People scored points (on a five-point scale) for how often they participated in mental activities such as listening to the radio, watching television, reading, playing games and going to a museum.

The more points scored, the more often people participated in mentally stimulating exercises.

During the next six years, the study found that the rate of cognitive decline in people without cognitive impairment was reduced by 52 per cent for each point on the cognitive activity scale.

For people with Alzheimer's disease, the average rate of decline per year increased by 42 per cent for each point on the cognitive activity scale.

Listening to the radio? Watching television???

Let me guess. The people without cognitive impairment were “reading, playing games and going to a museum” whereas those with Alzheimer's disease were “listening to the radio, watching television.”
